  • Device and method for estimating the resistance of the ground connection for an electrical apparatus
    Patent number: 9234858
    Abstract: A device and method for estimating resistance of a ground connection of an electrical apparatus connected to an electrical power network, also connected to ground by an additional resistance, and including at least one impedance disposed at an input of the electrical apparatus, a voltage generator connected to the impedance and connected to ground, a mechanism to measure current flowing to ground, and a calculation mechanism to estimate the resistance of the ground connection as a function of the current flowing to ground. The device and method can for example find application in estimation of resistance of a ground connection of a charger of an electric or hybrid traction motor vehicle.
